Server Room Cabling FREE cabling and networking Helpdesk

icon Server Room Cabling

I am trying to find some information on correct practices in a server room. Primarily concerned with something I recently noted..that power strips should not be used in a server room to connect multiple peripherals (hubs, routers etc.) to a Uninterruptible power supply. Additionally, the best practices for dealing with isolation of data cabling and power (line and various dc power cube transformer) cabling.

icon Hello Wil,
You are right - you should not use power strips to connect devices to UPS since it negatively affects reliability - the property that UPS is intended to improve.
If you look at the server room as a kind of telecom closet, you may apply the requirement from TIA/EIA -569 standard that says that you need two power feeders on separate 20A brakers to power telecom equipment plus one circuit for supplementary equipment like testers and other kinds of tools.
When it comes to separation of data cabling from power cabling, I would suggest that you read the document, just recently published by and called "Guide to Separation of Network Cabling from EMI sources". It contains plenty of useful references and other information that you may use considering data and power cabling separation. You may access the document by visiting this link:
With best regards,
